To all whom it may concern:

Be it known that I, J ULES BUFFET, a citizen of the Republic of France, and residing in Paris, France, have invented certain Improvements in Hydrocarbon-Burners for Furnaces, (for which -I have obtained French Patent No. 160,982, February 19, 1884; Belgian Patent No. 64,851., April 17,1884; British Patent No. 6,513, April 18, 1884; Italian PatentNo. 16.781,April 25,1884; German Patent N o.19,062,May 3,1884; Spanish Patent No. 6,167, April 21, 1884; Austrian Patent No. 30,217 October 24, 1884,) of which the following is a specification.

.This invention relates to apparatus for burning hydrocarbons in steam-boilers, furnaces, and similar heating apparatus by converting the liquid hydrocarbons into vapor by the atomizing action of steam.

My improved construction of hydrocarbonburner may be applied to any ordinary furnace or fire-place without alteration of the latter,so that either the usual fuel may be employed as before as the heating agent or the hydrocarbon-burner may be put into use, or both together.

In the accompanying drawings, Figure 1 is a vertical section of a portion of the end of a steanrboiler with my improvement applied thereto. Fig. 2 is an end View of the same. Fig. 3 is a vertical section of the vaporizing portion of the apparatus drawn to an enlarged scale. Fig. 4 is a detached view of one of the regulating-slides for the vaporizer. Fig. 5 is an enlarged sectional view of the heater portion of the apparatus and Fig. 6 is a view similar to Fig. 1, but with the burner moved back on its hlngc and shown partlyin section.

The apparatus is composed of two principal parts-namely, the heater B and the vaporizer or burner proper, A,which latter is hinged to the heater. The heater B is carried by a baseplate, B, which may be bolted to the masonry or the end of the boiler, as shown in Fig. 6. This heater consists of a chamber with an inlet, V, Fig. 5, for the supply of steam through the pipe V, Figs. 2 and 6, and with its exit at the lower end leading to the lower branch of the heater, over which is fitted the conical cap G, so as to be free to turn on the said branch.

Through the steam-chamber passes diagonally a conduit, H, which receives a supply of oil from the tank 0 through a valved pipe,H,and this oil finds its exit through the upper branch of the heater, on which is fitted a conical cap, G, free to turn thereon, as the cap G on the lower branch. Each cap G G is provided with a lateral branch, 9 g, to which is coupled a valved pipe leading to the vaporizer A, Figs. 2 and 6, that connected with the cap G having the pipe Hileading to the upper chamber, O, of the vaporizer,while the pipe V leads to the lower chamber, E, of the vaporizer. The vaporizer A,with pipes IF and V and caps G G, thus constitutes a structure which is hinged on the heater B, and can be turned from the position shown in Figs. 1 and 2with the vaporizer close up to the shield P, ready for use, or swung back to the position shown in Fig. 6, or even back to a position where it will have made a half-turn on its hinges. The upper and lower branches of the heater are provided with lateral openings 1) and I), respectively, Figs. 5 and 6, which coincide with the lateral branches 9 g of the caps G G when the vaporizer is turned to the position shown in Fig. 4 to be put in use; but when the vaporizer is turned back on itshinges the openingsbb are closed by the caps G G and the supply of oil and steam thus cut off. The chambers O and E of the vaporizer communicate with a box or chamber, 1), in which is a central partition,l\1,with a horizontal slot opposite it and serving as the discharge-opening. The size of the openings above and below the central partition may be varied by means of slides R and B/ within the chamber, and capable of vertical adjustment by means of eccentrics on the ends of the rods K K", Figs. 1 and 3, act ing on the blocks in in slots in the said slides. (See Fig. 4.) The front edge of the partition MI is beveled, as shown in Fig. 3, and the slides and partition are provided with notches or grooves to assist in dividing the spray of steam and oil. The outer ends of the spindles K are squared, and can be turned by suitable keys to adjust the slides B B/ to regulate the supply of steam and of the oil to be vaporized and burned.

The operation of the apparatus is as follows: WVhen the steam, supplied from any suitable generator, reaches a pressure of one and a half atmospheres, the vaporizer is turned on its hinges to bring the slotted discharge-box up to the opening in front of the furnace. The steam is then turned on first,'and afterward the hydrocarbon gradually, the hydrocarbon becoming heated in the passage through the pipe H in the ste'amchamber of the heater B. The slides R B are adjusted until the flame produced possesses the desired intensity and the combustion is perfect, which is made known by the total absence of smoke.

In the apparatus described it will be understood that there'is a fire upon the grate,which ignites the jet of the vaporized hydrocarbon but after a short time the heat of the furnace is more than sufficient to kindle the jet of oil and steam without the aid of other fuel. In all cases, even after a prolonged stoppage, a rag or little wood burning on the fire-bars is sufficient to ignite the jet.

\Vhere a number of generators are employed, the steam-pressure necessary to produce the spray may be derived from any one. of such generators in order. to produce a fresh source of heat for steam production or other purposes.

The quantity of steam consumed by the ap paratus is comparatively trifling.

I am aware that furnaces have been provided with swinging h ydrocarbon-burners, the hinging being obtained through the medium of union-couplings connecting sections of pipe. In my invention, however, I obtain a much more convenient and strong construction by hinging the vaporizer to the rigid structure of the heater, as described above.

I claim as my invention 1. The combination of the heater B and oil and steam supply pipes therefor with the vaporizer A, hinged to the said heater, as and for the purpose set forth.

' 2. The combination of the heater B and its branches and oil and steam-supply pipes with the vaporizer A, connecting-pipes H and V, and hinging caps, substantially as described.

3. The combination of the furnace,the baseplate B, secured to the said furnace, and the heater B,carried by said base,with the vaporizer A,hinged to the said heater, substantially as described.

4. The herein-described hydrocarbon-vaporizer, consisting of a slotted box having separate inlets for steam and hydrocarbon, a partition opposite the slot in the box, and regulating-slides, substantially as specified.

5. The combination of the. slotted box D, having separate inlets for steam and hydrocarbon, and a central partition opposite the slot in the box, with regulating-slides R It, having notches d, substantially as described.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

JULES BUFFET.
